SAVINGS-CLOCK.

Specification of Letters Patent. I Patented Apr, 27, 1920.

Application filed June 30, 1917. Serial No. 177,894.

To all whom it may concern Be it known that I, AAGE GEoRc PETER VVIINGAARD, a subject of the King of Denmark, and a resident of Copenhagen, Den- -mark, No. 3 Norrevold, insurance broker,

have invented new and useful Improvements in Savings-Clocks, of which the following is a specification.

This invention relates to a savings clock, 2'. e. a clock 'connected with a savings-box, and arranged in such manner that the clock stops after the expiration of a fixed time, unless a coin is introduced into a coin chute, which is so connected with the clock work that a device applied in the coin chute acts upon the clock work. In order to remind the owner of the savings clock, that the time for inserting an other coin has come, means are provided so that the dial, some time before the clock stops, is hidden by a cover on which is an inscription corresponding to the purpose. The moving parts of this cover are mechanically so connected with the other parts of the clock Work that the cover beingin closed position and no fresh coin being inserted, the cover will after a short time return to normal open position and the clock will again run for another period, but after a certain period the cover will again hide the dial and the'clock be stopped so that the dial only becomes visible when the owner has again inserted a coin into the coin chute.

It is to be noted that the mechanical arrangements which cover and uncover the clock dial may take a number of forms, and that which will hereafter be described may be regarded only as one example.

The invention is shown in the accompanying drawings in which Figure 1- is an elevation ofthe clock as seen from the back; all the arts unnecessary for the understanding of the invention being omitted, for instance, the clockwork proper with its ap urtenant wheels, sprin s, winding keys and so forth as well as tie clock casing and the coin receptacle.

-Fig. 2 is a similar view, but with the plates which are adapted to cover the clock dial in the closed position.

Fig. 3 is a side view of tant parts of the mechanism, and Fig. '4 is an elevation showing the cover plates and their moving members in the nor 11ml p n p sition.-

the most impor- Fig. 5 is a detail View of the disk which controls the moving members, and

Fig. 6 is a detail view of the holding hook for the cover plates.

Fig. shows a modified form of the cover plate, and

Fig. 8 shows another modification of the cover plate.

Referring to the drawings in detail, 1 is the back plate of the clockwork in which bearings are formed for the gear spindles for the various mechanisms;- I

The balance 2' of the clockwork cooperates with a stop 3 on an arm 4, which is rotatable upon a pivot 5. The stop isunder the tension of a small spring 6. The coin chute 7 has two notches 8 and 9 in which are adapted to enter. the bent ends -10 and 11 of a three-armed lever, the arms of which are indicated 12, 13 and 14. This lever is rotatable upon a spindle 15, and the arms 12 and 14 are adjusted in such a manner that the bent end of the one arm will extend into the coin chute, while that of the other arm is outside of the chute.

The free end 16 of the arm 13 so cooperates with a finger 17 on the arm 4 that a I turning movement of the lever 12, 13, 14 to the one side will lift the stop 3 from the balance 2, while a turning movement to the opposite side will lower it down against the sto The end of the arm .14 has a hook-shaped bend 18 (Figs. 3 and 4) which cooperates with a radial notch 19 in the disk 20 (Fig. 5) which together with a gear wheel 21 is mounted upon the spindle 22. The notch 19 is normally covered by a plate 23 rohave fixed crank arms 31 and 32, of which the arm 31 is connected by a link 33 with the one arm of the three-armed lever 34, 35, 38, the other arm of which is connected by a link 36 with the crank arm 32.

The lever 34, 35, 38 is rotatable upon a pin 37, and the third arm 38 has a screw 39, which travels in a slot 40 in an arm 41 (Fig.

' 6) the one end of which is linked, by means nose 45 which coiiperates with a pin 46 on will fall vertical? the rear side of the disk 20, the arm 43 bein acted upon by a s rin 47.

%)n the end of the 35 is a hook 49 rotatable around a pin 48, which hook is kept in the position shown on Fig. 1 by a small s ring 50, and the lever 34, 35 itself 1s m uenced by a small slpring 51 (Fig. 3).

On the arm 32 is a nger 52 (F1gs.-1 and 3) which cotiperates with the one end of a two armed lever 53, 54 rotata'ble upon a spindle 60, and the bent end of the upper lever arm 54 enters into a notch 56 in the coin chute 7. The arm is kept in the osition shown in Fig. 2 by a small spring 5 Normally all the movable arts occupy the he bent end 10- position shown in Fig. 1. of the upper arm 12 of the three'armed lever 12, 13, 14 retainst lrecoin introduced in the coin chute 7, and the arm 13 presses on the arm 17 so that the stop 3 is lifted from-the balance '2. The hook 49 has caughtthe bend 11, so, that the arm 34, 35, 38 occupies the position shown in Fig. 1 by which the two cover plates 25 and 26 are swun out in the open position. The wheel 21 wlth the disk 20 is turned slowly by the clockwork, in the same direction as the hands, so that the disk 20 makes one revolution, for instance, in 24 hours, and the bend 18 of the arm 14 is held in engagement with the rim of the disk 20 -by the tension of the spring 6.

During the turning of the member 21 the pin 46 Wlll graduall press against the nose 45 on the link 43 ig. 6) and thereby displace this lever system to the left, the screw 39 sliding in the slot 40. During the con tinued turningof the disk, the edge 58 (Fig. 1) of the small plate 23 engages the bend 18 on the arm 14, and thereby uncovers the extent that the bend 18 mayslip into the notch 19, the lever 12, 13, 14 will upon the bend 18 entering the notch be turned, owing to the spring 6 tending to lift the. arm 13. Thereby the arm 12 will turn to the position shown in Fig. 2 and release the .coin, which down through the coin chute and by its all strike against the bent end 11, which by the swinging of the arm 14 is projected into the coin chute. By the impact of the coin with the bend, this will be pushed back to the initial position, so that the forward and backward turning of the lever 12, 13, 14 will take place in the course of a very short time, for instance a second.

' Bythe swinging of the arm 14, the hook 49,

has, however, been released, whereupon the sprmg 51 will turn the lever 34, 35, 38, and swing the cover plates 25 and 26 to the closing position. a

As soon as the coin in falling has moved the bend 11 (Fig. 1 a the, left, the b nd s will be disengaged from the notch 19, and

the cover plate 23 will then instantly be turned bac to the initial sition by spring 24, and prevent the ever 12, 13, 14 from turning back again.

The two cover plates 25 and 26 will however not immediately nal position, but wil remain in the closed the I return to their origiposition until the pin 46 has turned so far,

that it ma slip behind the nose-45. The

link 43 an the arm 41 will then move to the w right (Fig. 6) operated why the spring 47-, i

and by the operation of the screw 39 on the arm 38 the three-armed lever 34, 35, 38 turns back to the position shown on Fi 1. I By determining the position of the pin 46, the ength of time the cover plates shall be down, may be predetermined.

.When it is perceived from the dial being covered that a fresh coin has to be inserted and that possibly the clock also requires rewinding, the introduction of a fresh coin in on the crank lever 32 turns the said lever and thereby the two cover plates back to cordingly omits to insert a fresh coin, the

covering plates will in the manner described after the expiration of a time again go back to the normal position, and the clockwork will again run for-another period, for instance, 24-hours. Then the notch19 of the disk 20 will again be uncovered, and the bend 18 will again eng'a e therewith, but as there is now no coinin t e coin chute, which by its fall ma turn the arm 14 and thereby again swing t e bend out from the notch 19, it will remain engaged and the arm 13 being raised, releases the finger 17 whereupon the stop 3 will turn down against the balance 2 and stop the escapement of the clock at the same time that the closing plates again come to ether and cover the dial.

y inserting a fresh coin in the coin chute, it will by its fall strike the bend 18 aside and thereby turn the arm 14, so that-the stolp 3 again releases the clockwork.

n Fi s. 7 and 8 are shown two modified forms 0 the cover disk for the clock dial.

In Fig. 7 this disk is shown arranged as'anlVhat I claim and desire to secure by Letters Patent, is: t
